In my opinion it doesn't look like an SCP as it doesn't possess any anomalous abilities, more like some terribly mutated animal in some failed bioweapon experiment. Besides, as ClockworkKitten stated, there are a lot of "monster" SCPs such as 682

I just wonder why Foundation personnel are allowed to wear it since it is kind of suicide, the rest are pretty interesting. I like how people who commited different crimes transformed into different things.

Dropped a C&D on the last one, since they're effectively 0 for 3 on worthwhile crit. They may be underage. Keep an eye on.
